Load Balancing cockpit error

Question

          We are testing clustering and load balancing using WLS 6SP1. We have found that
          the fail over works fine (i.e. we kill a server and the next call is invoked on
          another server). However, we find that all calls (modulo failover) always go to
          the same server. We expected to get round-robin for each home access. I've attached
          the config.xml and deployment descriptors. What am I missing here? Is there anything
          special I should be doing code wise?
          BTW: All calls are going to a stateless session bean.
          Regards,
          Andy

          Wierd, I've just managed to download it. Anyway, I'll paste the
          contents into the text below.

          We have a stateless session bean. At each request we use JNDI to
          obtain a handle to a stateless session bean. We invoke an
          operation on it and then call remove on the stateless session
          bean. We run several of these clients (Java clients) and observe
          the system load and network traffic. We see that network traffic
          is almost minimal and system load on the "other" server is non-
          existent. We know that other server can satisfy calls to the
          stateless session bean because fail over (between calls) works
          correctly. I'm sure we are doing something daft, but I can't spot it.
